I started exploring the use of oil paints on very slick satin-like heavy cardboard paper years ago. And I still try out ideas and certain images on this paper, mainly now with water based oil paints that are no so toxic to use directly with your hands on paper. This oil base paint let’s you work for a long time on the surface with gloves and I use palette knives to spread the colors and gestures on the paper’s surface. The toxic smells of older oil paints has almost disappeared and that gives you more freedom to work with this medium.
I will no doubt continue to experiment with this technique and have many ideas for series of small scale works based on figures and themes I already elaborate on a larger scale on paper.
